A pilot operating on the wrong radio frequency for Hokitika Airport narrowly missed a collision thanks to the actions of the ground crew.
The March incident between a privately-owned light plane and a Royal New Zealand Air Force aircraft has been highlighted in the Civil Aviation Authority's latest Vector magazine.
A Canterbury pilot flying to Okarito and on to Hokitika to refuel before returning back over the alps said he had been to Hokitika several years before when the radio frequency was 119.1 MHz, and an unattended airfield.
"After a short flight up the coast, I made the comment to my daughter that it was very quiet around Hokitika I knew there were a few microlights that fly out of there. But it was a weekday and maybe that's why it was so quiet on the radio.''
Approaching Hokitika they made two calls.
